• 15) VT7300 Stand-alone fan coil application using 3 levels of occupancy with a remote PIR sensor
Set-up and Configuration
Thermostat used VT73x5X5000 ( lodging models )
PIR used BI1 configured for remote PIR sensor
BI2 Configuration Door dry contact
Stand-by timer value Not used
Unoccupied timer value 6.0 hours
Network interface used None, stand-alone
Sequence of operation:
At initial power-up, when the thermostat 24 Vac power supply is applied; the initial occupancy of the zone will be stand-by
mode if the PIR device do not detect any movements.
As soon as the PIR device detects a movement or motion, the occupancy status switches to occupied and the occupied
setpoints are used. The room will then be in occupied mode until a door toggle is detected.
If a door toggle is detected, then the room switches to stand-by mode and the stand-by setpoints are used. If any occupants
are left in the room, local movements must be seen to resume the occupied mode.
While in stand-by mode, if no motion is detected in the zone for the entire unoccupied timer duration, then the room switches
to unoccupied mode and the unoccupied setpoints are used.
At anytime, if the PIR device detects a local movement or motion, the occupancy status switches to occupied and the
occupied setpoints are used.

Set-up and Configuration
Thermostat used VT73x5X5000 ( lodging models )
PIR used BI1 configured for remote PIR sensor
BI2 Configuration Door dry contact
Stand-by timer value Not used
Unoccupied timer value 0.0 hours
Network interface used None, stand-alone
Sequence of operation:
t initial power-up, when the thermostat 24 Vac power supply is applied; the initial occupancy of the zone will be stand-by mode
if the PIR device do not detect any movements.
As soon as the PIR device detects a movement or motion, the occupancy status switches to occupied and the occupied
setpoints are used. The room will then be in occupied mode until a door toggle is detected.
If a door toggle is detected, then the room switches to stand-by mode and the stand-by setpoints are used. If any occupants
are left in the room, local movements must be seen to resume the occupied mode.
At anytime, if the PIR device detects a local movement or motion, the occupancy status switches to occupied and the
occupied setpoints are used.
The local zone never goes into unoccupied mode and the unoccupied setpoints are never used.
